A general but still unknown characteristic of active oxygen evolution electrocatalysts
(Royal Society of Chemistry, 2023-04)
The unsatisfactory electrocatalysis of the oxygen evolution reaction (OER) is a major hurdle for the sustainable production of hydrogen using water electrolyzers. Besides, most state-of-the-art catalysts are based on ...
Self-propelling colloids with finite state dynamics
(PNAS, 2023-03)
Endowing materials with the ability to sense, adapt, and respond to stimuli holds the key to a progress leap in autonomous systems. In spite of the growing success of macroscopic soft robotic devices, transferring these ...
The Magnetostriction of Amorphous Magnetic Microwires: The Role of the Local Atomic Environment and Internal Stresses Relaxation
(MDPI, 2023-10-20)
We studied the magnetostriction coefficients, λs, Curie temperature, Tc, and their dependence on annealing conditions in Fe47Ni27Si11B13C2 and Co67Fe3.9Ni1.5B11.5Si14.5Mo1.6 amorphous glass-coated microwires with rather ...
Influence of the Geometrical Aspect Ratio on the Magneto-Structural Properties of Co2MnSi Microwires
(MDPI, 2023-10-04)
This present study illustrates the strong effect of geometrical parameters on the magneto-structural properties of Co2MnSi glass-coated microwires prepared using the Taylor–Ulitovsky method. Thus, there are three samples ...
Development of sensors for individual barium ion identification in the context of the NEXT experiment
(2023-06-23)
Esta tesis recoge los resultados obtenidos durante los primeros pasos en el desarrollo de un quemo-sensor de bario dicatión para el experimento NEXT. Su funcionamiento se basa en convertir propiedades químicas del analito ...
Unveiling the Magnetic and Structural Properties of (X2YZ; X = Co and Ni, Y = Fe and Mn, and Z = Si) Full-Heusler Alloy Microwires with Fixed Geometrical Parameters
(MDPI, 2023-10-29)
We studied Ni2FeSi-, Co2FeSi-, and Co2MnSi-based full-Heusler alloy glass-coated microwires with the same geometric parameters, i.e., fixed nucleus and total diameters, prepared using the Taylor–Ulitovsky method. The ...
Are ionic liquids effective curing agents for preparing epoxy adhesives?
(Elsevier, 2023-07)
This work compares for the first time the efficacy of using different ionic liquids (ILs) as epoxy hardeners in epoxy-based adhesives. Several phosphonium and imidazolium-based ionic liquids were tested as epoxy hardeners, ...
Cationically photocured epoxy/polycaprolactone materials processed by solution electrospinning, melt electrowriting and 3D printing: Morphology and shape memory properties
(Elsevier, 2023-08)
Epoxy/polycaprolactone (PCL) blends containing cationic photo-initiator were prepared by both solution and melt blending. These materials were processed by solvent casting, solution electrospinning (SE), melt electrowriting ...
Mechanical, electrical, and adhesive synergies in melt-processed hybrid bio-based TPU nanocomposites
(Elsevier, 2023-07)
Hybrid nanocomposites (NCs) based on a bio-based thermoplastic polyurethane (TPU) with multi-walled carbon nanotubes (CNTs) and graphene nanoplatelets (GNPs) as nanofillers, were obtained using a simple melt-mixing method. ...
Anomalous Magnetic Anisotropy Behaviour in Co-Rich and Fe-Rich Glass-Coated Microwires under Applied Stress
(MDPI, 2023-09-25)
In this article, we study the effect of annealing temperature and applied stress on the magnetic properties of Fe71.80B13.27Si11.02Nb2.99Ni0.92 and Co65.34Si12.00B10.20Cr8.48Fe3.90Mo0.08 microwires. An anomalous behavior ...
